ERIC 0. HAMREN, OF OSHKOSH, WISCONSIN, ASSIGNOR TO LEAGI-I COMPANY,OSHKOSI-I, WISCONSIN, A CORPORATION OF WISCONSIN TWO-WHEELED MIXER FRAMEApplication filed May 7, 1930. Serial No. 450,361.

This invention has to do with the twowheeled trailer frames on whichmixers of certain types are mounted.

One of the primary objects of the invention is to provide an improvedleg on which the front end of the frame is adapted to rest when themixer is in operation, which leg may be swung backwardly and secured inan out-ofway position when the mixer is in transit.

Another object of the invention is to provide an improved tongue bywhich the mixer may be pulled in transit, which tongue may be extendedforwardly and held rigidly when in use or may be telescoped back into anoutof-the-way position within the frame of the mixer and held there whenthe mixer is in operation.

Both the supporting leg and the draft tongue are simple, compact, andrugged in construction, are inexpensive to manufacture, and will standup under the most severe usage.

Other objects and advantages of the inven tion will be apparent to thoseskilled in the art upon a full understanding of the construction,arrangement and operation of the improvel ents above referred to.

One form of the invent-ion is presented herein for the purpose ofexemplification, but it will of course be appreciated that the inventionis susceptible of embodiment in other structurally modified forms comingequally within the scope of the appended claims.

In the accompanying drawings:

Fig. 1 is a partly sectioned side view of a tilting type concrete mixerequipped with the improvements of the invention, showing the leg andtongue in the posit-ions in which they are placed when the mixer is inoperation;

Fi 2 is a top view of the mixer frame, with the tongue and leg in thepositions shown in Fig. l;

Fig. 3 is a side view of the mixer, showing the leg and tongue in thepositions in which they are placed when the mixer is in transit;

Fig. 4 is a corresponding fragmentary side view, with portions of theframe broken away; and

Fig. 5 is a fragmentary front view, showing the supporting leg.

The frame shown in the drawings includes a pair of forwardly convergingsill members 10.0n which a mixing receptacle 11 and a motor 12 aremounted for operation. The front end of the frame is supported, when notin transit, on a centrally arranged leg 13, 5 while the rearend of theframe is supported on a pair of wheels 14: which are journaled on theends of an axle 15. The mixer, when .in transit, is drawn by a tongue16, which tongue telescopes back between the sill members of the frame,as shown in Figs. 1 and 2, when the mixer is in operation.

The leg 13 is U-shaped, and the upper ends of the sides of the same arepivotally attached to the front ends of the sill members '10 by a pin17. A cross rod 18 is rigidly attached to the sides of the leg near thetop of the latter and constitutes .a support for the tongue. The bottomof the leg is flat and is outspread to a greater width than the top, asshown in 7 Fig. 5. A curved bracing link 19 is pivotally attached to theleg 13 by a pin 20 and rests upon a cross rod 21 which is carried by theframe. The link 19 is provided with two spacednotches 22 and 23 whichare adapted to hook over the rod 21, whereby to lock the leg rigidly ineither the vertical supporting position shown in Fig. 1 or the raisedout-ofthe-way position shown in Fig. 3.

The tongue 16 is achannel bar which is bent upon'itself and is arrangedwith the bend at the front to form a coupling loop 24. When the tongueis in the retracted position shown in Fig. 1, it'rests upon the crossrods 18 and 21 and is held against forward movement by a verticallyshiftable latching plate 25. The plate 25, which is loosely attached tothe front end of the'frame by a bolt 26 which extends through avertically elongated slot 27 in the plate, extends downwardly in frontof a small cross web 28 in the tongue and prevents the latter fromsliding forwardly. When the tongue is to be used, theplate 25 is raisedand the tongue is slid forwardly into the position shown in Fig. 3, inwhich position two hooks 29 on the rear ends of the spaced sides of thetongue engage about the-cross rod 21. The sides 30 of the tongue at thelocations of the hooks are spread apart sufficiently to engage with theinside faces 31 of the side members 10 of the frame, as shown in Fig. 2,whereby to prevent the tongue from swinging horizontally with respect tothe frame when in its forwardly shifted position. After the hooks 29have moved into engagement with the cross rod 21, the latching plate 25is lowered into a position between two closely spaced cross webs 32 inthe tongue, whereby to prevent the tongue from shifting rearwardly. H

It will be noted that the arrangement of the hooks 29 and the cross rod21 with respect to the lower edge of the front end of'th'e frame and thecross rod 18 is such as to cause the tongue 16 to extend downwardly andf0rwardly at an inclination to the frame 10. As a result of this, whenthe front looped end 24 of the tongue is raised and attached in asubstantially horizontal position tothe vehi dc to be used in pullingthe mixer, the frame 10 of the latter will be tilted rearwardly into aposition similar to that shown in Fig. 3 and the weight of the load onthe frame'will be substantially counterbalanced, thereby relieving thetongue 16 from any appreciable weight. After the tongue has beenattached to the front vehicle, the leg 13, which is then clear of theground, is of course hooked back into the position shown in Fig. '3.lclaimz' 1. In a vehicle, a wheeled frame, adraft tongue slidablymounted withinthe frame for movement longitudinally thereof into eithera forwardly projected position or a rearwardly retracted position, andreadily releasable means for locking the tongue against longitudinalmovement in either its projected or retracted position, said meansconsisting of longitudinally spaced abutments on the tongue and avertically shiftable latching member on the frame for coaotion witheither of said abutments.

2. In a vehicle, a frame having wheels supporting one end thereof, asupporting leg pivotally mounted on the frame adjacent the other endthereof, a tongue slidably mounted within said frame, a cross member onsaid frame supporting said tongue, hook means on said leg forcooperation with said cross member, and hook means on said tongue for cooperation with said cross membe In witness whereofI have hereunto subscribed my name.
